Abstract
This study addresses the problem of uncertainties of total CO 2 emission intensities estimated using an input–output (I-O) table for a life-cycle inventory analysis. The validity of the total CO 2 emission intensities has been questioned mainly because the amounts of commodities are measured in monetary units, and because various commodities are produced in a single sector of an existing I-O table. In this study, first, a sensitivity analysis of total CO 2 emission intensities estimated using the Japanese I-O table was performed to identify the elements that significantly influence the total CO 2 emission intensity. If an influential element identified by sensitivity analysis varies widely, the total CO 2 emission intensity is greatly influenced. Secondly, how much total CO 2 emission intensities vary associated with the variation of those influential elements was evaluated. It was concluded that the evaluation of uncertainties using a stochastic approach as well as the improvement of accuracy by disaggregating the original I-O sectors, focusing on influential elements, are important.
